Comments on FDA Draft Guidance on Postmarketing Studies and Clinical Trials

October 13, 2009

Docket No. FDA-2009-D-0283

Division of Dockets Management (HFA-305)
Food and Drug Administration
5630 Fishers Lane, Room 1061
Rockville, MD 20852

Public Citizen has reviewed the draft guidance in detail and supports its purpose and approach. The guidance makes a sensible distinction between studies that are for efficacy purposes only (“postmarketing commitments”; these may be recommended but not required) and those that have any significant safety element (“postmarketing requirements”; these may be required). The categories of studies that can fall under postmarketing requirements (observational studies, clinical trials, animal studies, in vitro studies, pharmacokinetic studies, and interaction/bioavailability studies) are appropriately broad. We urge you to resist any efforts to weaken the draft guidance.
